Apple advises developers that CloudKit data, including iCloud Drive, Photo Library, and Mail Drop will be wiped on July 7

Enjoying the betas for iOS 8 and OS X Yosemite? Just a heads up that Apple has warned developers that a server-side data wipe will be happening on CloudKit public and private databses. This wipe will take place in three days on July 7.

Here's the message going out from Apple:

Dear Developer,

We will be performing a server-side data wipe on all CloudKit public and private databases for iOS 8 beta and OS X Yosemite Developer Preview users on July 7, 2014. The following iCloud features will be affected: iCloud Drive, iCloud Photo Library, and Mail Drop.

Photos and videos stored in iCloud Photo Library will remain on their original iOS 8 devices and will upload to iCloud Photo Library again automatically. iCloud Drive can be re-enabled from Set up Assistant after upgrade. If you choose to store your documents in iCloud Drive, your Documents & Data will automatically be copied to iCloud Drive. iCloud Drive will not update across earlier seeds or operating systems. Attachments sent through Mail Drop will expire and need to be resent after you upgrade.

If you have any questions, visit the Apple Developer Forums.

Best regards,
Apple Developer Technical Support

Just a friendly reminder in case you're wondering where your data in the clouds went. Don't fret too much as the data will upload automatically again from your devices after the wipe.

Are you looking forward to the release of iOS 8 and Yosemite? Sound off below!

Let me just laugh at you! I got almost 300 application with 640 songs, 1,800 picture and 40 videos on my 64GB iPhone 5S with iOS 7.1.2 and my iPhone still running very good. Plus I was using iOS 8 beta 2 but I downgraded because some applications still crashing "yea because it is a beta version" I don't know why people jailbreak iPhones whenever you going to buy any smartphone if you don't like it the way it is don't buy it. At least that my point of view!
